An increasing number of applications today require high precursor temperatures, often up to 220°C (428°F), with very tight temperature controls. System designers may specify an oven enclosure for the entire gas system to precisely control these high temperatures. This demands a valve that can be entirely situated within the high temperature environment, including the body and actuator.
Swagelok® thermal-immersion diaphragm valves offer high-speed actuation, flow coefficients up to 0.60, and are designed for optimum performance at 220°C (428°F) for high-temperature processes including atomic layer deposition (ALD) and precursor delivery applications. They are offered in both pneumatically actuated and manual models with a variety of 1/4 and 3/8 in. end connections.
